Please reread my prior post. I have just installed from the current KDE-Lite 32 bit. I did absolutely nothing to the default configuration of KDE or anything else. First boot was fine. Did a dist-upgrade and now have the exact same symptoms as seagull, i.e. cannot login to KDE, kwin repeatedly crashes and I get the same error/bug report windows as seagull. Installed LXDE from the command line and can login to LXDE from kdm just fine. I have a GeForce 9400 GT graphics card and am running the stock nouveau driver that is installed by default.

From the above, one can conclude that this is not a 64bit only problem and it is not caused by any odd plasmoids or experimental packages as I installed none; I just did a dist-upgrade after a fresh install to bring the system up to date.

Same problem here on a fresh install of 2011-kde-min. Changed nothing from the default kde setup; first boot was fine; did a dist-upgrade; on reboot have the identical problem as seagul. Running 32 bit, with the nouveau driver.

Same problem here on a not-so-fresh install. Running 32 bit, with the nouveau driver. Followed devil's earlier advice and downgraded libdbus-1-3 to testing and put a hold on it. Works fine now. Thanks devil!

I stole the following from somewhere on the site and edited it to suit my needs.

I've just started having, today, what might be a related issue: With or without my dual-monitor setup, if I log into a kwin-associated manager (like XFCE4 or KDE), the monitors soon go dark and enter "power-saving mode".

Logging in via ssh from another computer shows that the x-manager still runs, and I can correctly forward various windows to the other computer (e.g. konqueror works just fine).

I tried putting libdbus-1-3 on hold, downgrading, and all of that, with no luck.

I also reinstalled the Geras XFCE version. This works fine until I try to dist-upgrade (even with libdbus-1-3 held), whereupon a restart gives me the same dying monitors problem.

Mine occurred after doing upgrade with smxi. I did not have any issues with previous kernel. However I upgraded also to a new nVidia graphics card. Its a GTX 560 Ti. Could this bug be related?
Also if I remove the nvidia driver and go back to the regular xorg driver, would this temporarily solve the problem? I cannot get in to the GUI at all. The kwin crash error persists and does not go away.

Be advised if you use 3rd party scripts you are basically on your own...just a heads up, as the aptosid team does not support systems that are maintained using any such 3rd party scripts.

THANK YOU!!!!!!!!!!!!
My dist-upgrade from yesterday left me with an unusable computer, downgrading libdbus as described above fixed it.
/me bows to the wizards on this forum

What version of KDE you running?

A dist-upgrade today included two libdbus packages which have corrected the problem for me. I can now login to kde.
